Choose Your Pump by Application
What the pump has to move matters more than the brand on it. Start with the job, then match flow to the head height you are actually lifting against.

Little Giant 1-42 Water Pump is a compact oil-filled direct drive pump that works submersed or in-line — a dual-purpose design that suits fountains, water displays, and water transfer where a fully submerged pump isn't practical.
Key Specifications
- Flow: 205 GPH at 1' lift
- Motor: 1/150 HP, 115V direct drive, oil-filled with thermal overload protection; continuous duty
- Maximum lift: 7.4' shut-off head
- Installation: operates submersed or in-line (fed by pipe or hose)
- Connections: 1/4" MNPT discharge; 1/2" MNPT and 1/4" FNPT intake
- Construction: epoxy-coated cast aluminum housing, nylon volute and impeller, nitrile shaft seal
- Cord: 6' power cord
Which application is it right for?
Choose the 1-42 when you need in-line capability or a rugged little transfer pump. For fully submerged fountain duty with a longer cord, see the 1-AA-18 (18' cord); for more lift, the 2E-N (300 GPH, 11.8' lift). Email Info@fountaindepot.com for sizing help backed by 50+ years of fountain experience.
Shipping & Returns
Ships across Canada from stock — delivery typically takes 3 to 5 business days depending on province. Uninstalled units qualify for return within the applicable return period; contact us to arrange.
How do I size a pump for a waterfall?
Two numbers: the width of the spillway and the height you are lifting to. Wider spillways need more flow to look full, and every foot of rise cuts what the pump actually delivers.
Published flow ratings are measured at zero head - a pump rated 4,000 GPH delivers considerably less at eight feet. Send us the width and the height and we will size on real delivery rather than the number on the box.
What is a solids-handling pump and do I need one?
It passes debris rather than screening it out. If your pond is skimmer-fed, stocked with fish, or collects leaves, you want one - a screened pump in that setting clogs between visits.
For a clean statuary feature or a self-contained urn, solids handling is unnecessary and a compact pump is the better fit.
How much flow does a pond need?
A common working target is turning the volume over roughly once an hour on a stocked pond. Lightly stocked ornamental ponds tolerate less; heavily stocked koi ponds want more.
Waterfalls are sized differently - on flow per inch of spillway width rather than on pond volume. If you have both, size for whichever is the larger duty.
Can I use a Little Giant utility pump in my pond?
Generally not the right tool. The Little Giant utility and magnetic-drive units here are process and transfer pumps built for specific fluids and duty cycles, not continuous pond circulation.
If you are moving anything other than pond water, tell us what it is - seal and housing material compatibility matters and the wrong choice fails quickly.
Does the pump come with fittings or a fountain head?
Some do. The statuary and fountain kits arrive with a head ready to run. Most pond and waterfall pumps ship as the pump alone.
Check pump parts and accessories for fittings, or tell us your pipe size and we will include what you need.
Should I take the pump out for winter?
It depends whether the feature runs through winter. A pump left in a pond that freezes solid around it will be damaged.
If you are shutting down, the pump comes out, gets cleaned and is stored somewhere above freezing. If you are running through, we will advise on what the setup needs - ask before freeze-up.
